Application
Used as fire extinguishing equipment, may be connected to drinking water or industrial water systems PN 10 as follows:
- Connecting flanges DN 65125 PN 10 ISO 7005-2; DIN 2501; BS EN 1092-2;
- To PEHD pipe with socket and locking sleeve;
- Connecting flanges DN 65125 DIN 28604 PN 10 for ductile iron pipes.
- It has been designed in order to operate in difficult working media, industrial areas, seaside or hot climate.
Design and working characteristics
The underground hydrant HSX is manufactured in conformity with STAS 695 issued in cooperation with Firemen’s Committee. Allows the connection of portable hydrant STAS 698 or the connection of portable hydrant with valves STAS 697.
The hydrant has the following functions:
- shutting-off/opening – by operating hydrant stem with a special driving key (STAS 696), the operating stress being low;
- at opening, the draining system shall be completely obtruded , internal parts design assuring a minimum head loss, and at shutting-off the draining system shall be opened in order to allow water removal from the hydrant;
- complete hydrant disassembling and spare parts replacement may be easily performed;
- freezing protection – hydrant internal part, being above the main seat, shall be released of the water remained after operation. The bore located at the lower part assures an inside draining within max. 10 minutes. Waste water volume remained into the hydrant after complete draining will not exceed 50 cm³;
- disc gasket may be replaced without hydrant digging out.
Data to be submitted with the order:
User shall specify: execution variant, nominal diameter, burying depth, type of connecting flange.2. SURFACE HYDRANT “FOCUS” TYPE Application:
